Having owned a number of GoPros, I made the same switch last year.
The Insta360 has super annoying/intrusive software that always feels like it's trying to sell me something, but it's pretty excellent in terms of actual video quality.
I don't really use the software, not even for updates.
I copy out the footage directly using a USB-C cable (wish it had USB 3.0), and do firmware updates by just dropping the update file into the microSD card.
It's friggin' fabulous that everything is doable without having to use an app. (Also the app takes up somewhere between 1-2GB of storage on my phone, and I don't have that kind of space.)
